Evaporation Condensation Precipitation Runoff Water constantly moves from the Earth’s surface into the air and back again. This process is called the water cycle. Sunlight provides the energy for water to move through the water cycle. Water changes form when it is heated or cooled. Water can exist as a solid (ice), liquid (rain), or a gas (water vapor). Condensation As water vapor rises into the air, it cools causing the vapor to turn into tiny water droplets and form clouds. This change is called condensation. Precipitation As these tiny water droplets in the clouds join together they grow too heavy and fall to Earth as rain, snow, sleet or hail. This process is called precipitation. snow rain rain sleet snow Heat from the Sun causes liquid water on the Earth’s surface to change to water vapor or gas. This is called evaporation.
